TO ALL PERSONS TO WHOM THESE PRESENTS MAY COME:

Be it known that I, THOMAS F. BROWN, Jr., of Concord, of the county ofMerrim'ack, and State of New Hampshire, have invented an AdjustableTrimming or skein-Holder; and do hereby declare the same to be fullydescribedin the following specification, and represented in theaccompanying drawings, of which Figure 1 is a top'view, and Figure 2 alongitudinal section of it. Figure 3 is an edge elevation of it, asarranged in a skein of braid.

' Braid or tape, as put up for sale in the market, is generally wound ina skein. It is customary for the purchaser, preparatory to using it, tounravel it and wind it on a card, or in a ball. The purpose of myinvention is to save the necessity of doing this, and to enable a personto use the braid or't'ape in the skein.

In the drawings, A and B are two long isosceles-triangular plates, eachbeing furcated, or formed with a notch, a, in itsshortest side.

Each plate also has a long slot, 8, arranged longitudinally in it.Furthermore, each plate has a notch, b, in its vertex.

. At that end of the slot next the vertex of each of the plates A B is abolt, C, whose head, a, is square, and sunk in the plate. These bolts gothrough the two slots and washers d 11, arranged in manner asrepresented, the bolts being riveted down upon the washers.

Anelastic cord or spring, 1), goes through each of the vertex notches b,and the two slots, in manner as shown in fig. 2, the two ends of thecord being united or tied together. This elastic cord serves, by its contractile power, to move the two plates in opposite directions,longitudinally of each other, while they are held in connection by thebolts and'washers, arranged as above explained. The. apparatus so mademay be readily contracted lengthwise, so as to enable a person tointroduce it into a skein. After having been placed therein,

in which case the skein will .be reeled, as it were, on the holder, antity or quantities as occasion may require.

the two parts A B will be moved by their spring, so as to distend theskein and hold it in their larger notches,

d may be removed therefrom in such quan- I, claim the combination of.the plates A B, slitted and notched, as described, with theirconnections and operative spring, arranged and applied to. themsubstantially as specified, the whole bein g for the purpose asexplained.

THOMASS. BROWN, OF POUGHKEEPSIE, NEW YORK.

IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 81,472, dated August25, 1868.

To all whom it may concern:

Be it known that I, THOMAS S. BRowN, of Poughkeepsie, county ofDutchess, and State of New York, have invented a new and usefulImprovement in Clutch Mechanism for Harvesters; and I do hereby declarethat the following is a full, clear, and exact description of the same,reference being had to the accompanying drawing, making a part of thisspecification, in which- Figure 1 is a plan view of the invention. Fig.2 is a front elevation of the shippinglever andsliding fork.

Like letters refer to like parts in both figures.

My invention consists of a novel device for engaging and disengaging aclutch with a shaft, for the purpose of throwing the cutters in and outof action by means of a shippinglever, reciprocating fork, and spring,whereby the clutch and clutch-wheel, when disengaged,

are prevented from being accidentally thrown .into gear by the jar ofthe machine in passing over rough and uneven ground, or from othercause, and when engaged with the shaft the usual friction and consequentwear of the fork in the groove of the clutch are obviated.

In the accompanying drawings, A is a shaft,

to which the power is applied. B is a drivingpin upon such shaft. 0 is awheel, to which motion is to be imparted; The hub of the Wheel 0 isratcheted on the end adjacent to the driving-pin B. The other end of thehub is provided with a groove, D, to receive the sliding fork E, bymeans of which, when operated by the shipping-lever F, the wheel 0,sliding on the shaft A, is engaged with or disengaged from thedriving-pin B.

F is a shipping-lever, having a cam or eccentric slot with a notch orrecess at G. H is a pin on the sliding fork E, fitting into and operatedby the eccentric slot in shippinglever 13. I is a spiral spring, whichanswers the twofold purpose of keeping the wheel 0 in position whenengaged or clutched with the driving-pin B, and also of forming part ofthe device which constitutes the lock, and holds the same wheel inposition when it is disengaged from the driving-pin.

It willreadily be seen that when the wheel 0 is disengaged from the pinB, and the sliding fork is thrown back so that the lever F assumes theposition shown inFig. 2, the pin H having entered the notch G, the lowerarm of the lever stands at such angle from its fulcrum at K that theefiect of the pressure of the spring, applied through and by means ofthe fork E and pin H, is to keep the pin firmly in the notch, andthereby lock the lever in such position as to effectually prevent theclutch or ratchet from becoming accidentally engaged with thedriving-pin, while, at the same time, a slight pressure upon the upperend of the lever will disengage the lock and allow the wheel to becomeengaged with said driving-pin.

It will also be seen that the usual friction and consequent wear uponthe groove D and fork E are entirely obviated by my arrangement,because, when the wheel G is in gear, the pressure of the spring I isexerted against the wheel 0 and the pin B, leaving the fork loose andfree in the groove; and although, when the wheel is detached or out ofgear, the pressure is exerted against the fork, yet the wheel is atrest, and of course there can be no friction between the parts.

Having thus described my invention, what I claim, and desire to havesecured to me by Letters Patent, is-

1. The shipping-lever provided with a cam or eccentric slot and notch,to receive the pin. on the sliding fork, when constructed and operatingsubstantially as set forth.

2. The combination of the slotted and notched lever with the spiralspring and the sliding fork, when constructed and operatingsubstantially as set forth.

3. The combination ofthe slotted and notched lever with the spiralspring, the sliding fork, and the wheel having a grooved and ratchetedhub, when constructed and operating substantially as set forth.

In testimony whereof witness my hand this 27th day of June, 1868.

THOS. S. BROWN.
